I have to think fabricators are calling with questions (and putting
the job on hold) when shorted nets aren't specified in the fab drawing
If you design power systems with force/sense lines, it is faster/safer to check the sense location if the short is a physical component. ATE testing of a 120-pin PMIC device with 16-30 different regulators for portable devices has lots of sense lines. Ultimately, deliberate shorts have to be visible, controlled, and verified on the schematic/netlist level.
MGCDesignArchitect has a "net alias" function allowing you to connect two nets together. But, which net will get exported to layout as the other netname never leaves the schematic causes extra work (schematic pages are compiled in numerical order. Net name assignment isn't random. But, it may as well be.) Engineers have no easy way of finding where the designer put the sense line junction on a power net.
Deliberate-short components can be safe and save time in some situations. Fabricator seems to like running CAM on a board with zero shorts, then merge the shorting artwork.
Our default template for fabrication drawings specifies merging short artwork after cam DRCs to copper artwork. It works for us. Our design review process focuses on a DRC report with zero errors, zero override.
If we have to, we'll list the shorted nets on the fab drawing.
